Filling in the holes

A few ideas to fill in the page for the single straight feather stitch came up to mind as I had read some of the more recent lessons from SharonB's class. The other night with no thread to do my grid, I finally had an opportunity to try them. I might have pushed the limit too far on the 3rd light blue border and reduced it to nothing more than a fly stitches. But it's too late for, it's stitched!
